Abstract

A finite-element-based three-dimensional field solution for the magnetically saturable chokes that are used in many industrial electronics systems is presented. The inductances computed based on the finite-element field solution are compared with the estimated nonlinear inductances from actual measurements. The results show the adequacy of the three-dimensional finite-elements simulation. The results of the field solution are used to study the factors that influence the nonlinear characteristics of the chokes, such as the air-gap geometry, the equivalent winding turns and the property of material anisotropy.<>
